WIND-MOTOR.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed November 27, 1908. Serial No. 464,603.

To all whom it may concern:

Be itknown that I, Fran 018 IV. Darren, a citizen of the United States,residing at Richmond, in the county of lVayne and State of Indiana, haveinvented certain new and useful Improvements in lVind-h lotors, of whichthe following is a specification.

The object of my invention is to produce a multiple power member,ornmltiple-unit wind motor, especially adapted for use in piano playingmechanisms, in which a motor of any desired capacity may be built upfrom a plurality of motor units which, in their major details, are, forconvenience in manufacture, identical, the several units being securedtogether by ordinary screws into a unitary and complete structurewithout the necessity of any backing or connecting member.

The accompanying drawings illustrate my invention as embodied in afour-unit motor.

Figure l is a valve-side eleva ion; Jig. 2 a section on line 22 of Fig.3; Fig. 3 a section on line 3 3 of Fig. 1, and Fig. 4 a section on line4-4 of Fig. 1.

In the drawings, 10, 11, 12 and 13 indicate the main body blocks of fourpower pneumatics. These body blocks may be of wood or other suitablematerial and to one face of each is hinged a plate 14 by means of an airtight flexible hinge member 15. The sides and free end of plate 14 areconnected to the main body of the pneumatic. by means of a bellowsconnection 16 of ordinary construction. Secured to the free end of eachplate 14, by any suitable means such for instance as a screw 17, is anarm 18 to which is pivoted a pitman rod 19 journaled at its free endupon one of a series of cranks 20 carried by or formed integral with thecrank shaft 21. To this extentthe several units are identical thusfacilitating their rapid and cheap manufacture.

In order to produce a four unit motor the several units aredifferentiated in the following manner. Formed in the inner face ofblock 10 is a pocket which extends into but not through the block andcommunicates with a transverse passage 26 which leads to one side edgeof the block so as to register with a similar passage 27 extending transversely into the block 11 from one side edge. Similarly block 11 isprovided with a pocket 28 which is like pocket 25, extending into theblock 11 from the inner face thereof. Block 12 is provided with a pocket29 and block 15'is provided with a pocket 30, said pockets 29 and 30being like pockets 25 and 2S. Extending into block 12 from one side edgeis a passage which registers ith a passage extending into one side edgeof block 1 3 and communicating with pocket The passage 34 is formedentirely through block 13 from one side edge to the opposite side edgeand registers with a passage which extends entirely through block 12from one side edge to the other side edge and registers with a passage86 which extends into but not through block 11 although, in practice,the passage 36 might be continued through block 11 without harm as willbe apparent. Secured to block 13 around the outer end of passage is anipple 37 adapted to receive the usual suction pipe ordinarily found inpiano playing mechanisms.

Formed in the outer face of block 12 are three passages 41, 42 and 43which lead respectively into passages 32, and pocket 29. Similarly Iform, in the outer face of block 11, three passages 44, 45 and 46 whichlead, respectively, to passages 27 and 36 and pocket 28. Secured to theouter face of the blocks 11 and 12 are guides 47 between which aremounted ordinary D-valves 48 and 49, the valve 48 cotiperating with thepassages 41, 42 and 43 and the valve 49 cooperating with the passages44, 45 and 46. Secured to valve 48 is an arm 51 to which is pivoted anarm 52 which, in turn, is connected to one end of a rod 58, the oppositeend of said rod being pivoted to that pitman 19 which is connected tothe plate 14 of block 12. Similarly, valve 49 is provided with an arm 61to which is pivoted an arm 62 secured to one end of a rod 63 theopposite end being connected to that pitman 19 which is connected to theplate 14 of block 11. The valves and their connections are identical,thus cheapening manufacture. The two cranks, to which are connected thepitman 19 carrying rods 58 and 63, are set quartering so that, afterpassage 41 is uncovered by valve 48, passage 46 will be uncovered byvalve 49 by the time valve 48 begins to close passage 41, and valve 48will uncover passage 43 and be ready to start on its return at about thetime when passage 44 is uncovered by valve 49.

In order to connect the several units into a completed structure in thesimplest possible manner and at the same time give perfect freedom ofmovement of the plates 141, I secure blocks 11 and 12 together by meansof clan'iping screws 71 which pass edgewise through block 12 into block11, a suitable spacing plate 7 2 being interposed (as clearly shown isFig. 2) and faced, if desired, by leather or other suitable packingmaterial. Block 13 is then secured to block 12 by means of clampingscrews 73 with an interposed spacing plate 7 1-,and block 10 is securedto block 11 by means of clamping screws 75, the spacing plate 76 beinginterposed. Secured to the outer corners of blocks 10 and 13, preferablyby means of screws 77, are arms 78 in the outer ends of which the crankshaft 21 is ournaled.

I claim as my invention 1. A motor comprising a plurality of separablepower pneumatics arranged edge to edge and secured together, one toanother, with inlet and exhaust passages to said pneumatics extendingtransversely thereinto from the edges, a crank shaft, a pitmanconnecting each of the pneumatics to the crank of said shaft, and valvemechanism connected to said crank shaft and controlling the inlet andoutlet passages.

2. A wind motor comprising a plurality of separable power pneumaticshaving sim1-' larly shaped bodies, spacingblocks arranged between eachpair of main bodies, clampingscrews passing edgewise through one mainbody into an adjacent main body to clamp said main bodies together uponthe interposed spacing block, a crank shaft ournaled on said mainbodies, connections between said crank shaft and the movable member ofeach pneumatic, and valve mechanism connected to said crank shaft forcontrolling the inlet and exhaust passages of the pneumatics.

3. A wind motor comprising the power pneumatic 10 having passages 26 and25, the pneumatic 11 having passages 27, 28, 36, 44:, 4-5 and 4 thepneumatic 12 having passages 29, 32, 35, 411, 42 and L3, the pneumatic13 having passages 30, 33 and 3%, the said four pneumatics beingseparable and independent, the spacing plates interposed between eachpair of pneuinatics, the clamping screws passing edgewise through onepneu matic into the adjacent pneumatic to clamp the same together, acrank shaft journaled in suitable bearings carried by the pneumatics, apitinan connecting the movable member of each pneumatic with the crankshaft, the D valves 48 and 19, and connections between said E valves andthe crank shaft, all substantially as and for the purpose set forth.

In witness whereof, I, have hereunto set my hand and seal at Richmond,Indiana, this 21st day of November, A. D. one thousand nine hundred andeight.
